John, who has been Sonardyne International’s Managing Director since 2009, is staying within the Sonardyne family, taking the role of CEO of Sonardyne Group, the newly formed parent company of Sonardyne International and its sister companies; Chelsea Technologies, EIVA, Wavefront and 2G Robotics.

“This is an exciting time for Sonardyne International,” says Graham. “Looking beyond the current, uniquely challenging business climate, we’ll continue to grow organically, in terms of our people, our technology offering and the global markets which we support - while upholding the service and support that we’re renowned for. But we’re now part of a wider group of companies, with access to a considerably enlarged portfolio of products and services that complement our own seabed-to-shore systems. We expect this to deliver significant operational benefits for our customers across the global energy, ocean science, civil and defence markets.”

“Next year will be Sonardyne’s 50th year in business and I’m proud to have played a significant role in the success of the company over the last two decades,” says John. “As we look forward to celebrating that half century milestone with Graham at the helm, our collective sights are focussed on the direction we’re headed in at the start of our second half century. As CEO of Sonardyne Group, I’m excited at the prospect of working with Graham and his counterparts across our business to support those who measure, navigate, communicate or explore the world’s waters and oceans, safely, responsibly and more efficiently than ever before.”
